While I personally wouldn't attach a non A-branded charger to my iPhone, theoretically if the charger delivers 5V and does it on a USB connector, it really doesn't matter from where the power comes. The more amps the faster your iPhone will charge. I've been charging my iPhone with my iPad charger for years without any problems. Currently Apple has 3 ...

Small variations in the reported maximum battery capacity are perfectly normal, and don't mean that your battery is actually regenerating itself.

There are a lot of possible explanations. The indicator that reads battery status isn't a perfect measure. I've seen that kind of behavior on mobile phones (uneven discharge followed by a "full charge" don't necessarily give a perfect indication of actual battery capacity). Given that the difference you observed is around 150 mAh (out of 8755?), the ...

So - looking over http://www.apple.com/batteries/maximizing-performance/ you should see that charging warms the device and your measured temperatures risk the device shutting itself off and permanent damage to the battery. Yes, the battery is replaceable, but there's risk and cost there. I would tether over bluetooth or WiFi and disconnect the USB so that ...

Well, shave my whiskers, crumble my biscuit, and oil my gears, I'll be darned! I let it sit there in that state for a literal hour (72 minutes) with no progress bar or evidence of activity [even over USB 3.0!] and it eventually restored and booted. I still had to go through some prompts to get it to connect, but it worked.

I have a MacBook Pro (13-inch, Mid 2010) and the battery cycles counts more that 1100. Maybe I'm lucky, but I never change the battery and I think is working very well. (The System Information report a Condition that is Normal!) After the 1000 cycles the battery probably start and continue to decrease a bit the Full Charge Capacity but you can still use it. ...

Ok, I solved the problem. The computer socket where the charger was going in had some pencil marks in it. My friend just used a pencil eraser inside it, and then blew out the rubber, and it works like new.

Do you have another charger? If yes and if that works, maybe your first charger was damaged. Maybe there's a wire inside of it has broken or something, or the charger became loose (in wires or plug). But if you tried another charger and nothing happened, maybe the problem is in you laptop.

No. 5-7 days is way less than an extended period of time @FoamyBeer refers to. Imagine that a lot of devices stay in warehouses longer than the time you want not to use your MBP. Just handle it as if it was a book: Don't drop it Neither heat nor freeze it Keep it dry In addition to that, do NOT leave it with a discharged battery. Actually, it's no big ...

Apple's advice if you're storing a device for extended period of time, is: do not fully charge or fully discharge your battery, but charge it around 50% Power down the device Place in a cool moisture-free environment that's less than 32° C (90° F)

It is, to the best of my knowledge, complete nonsense that on a newish macbook pro and air, that keeping it plugged into the wall damages the battery. It was the case on older pc laptops, and most probably older macs too, but the newer macs are intelligent enough not to keep pumping power into the battery once it's charged. Once the battery is fully ...

Most likely the battery has died or is no longer being recognized by the system. To verify it is not the latter Apple has a KB article that will help with resetting the SMC. If it is the former it's time to replace the battery. If you are under warranty take it to a nearby Apple store. If not they can still do the repair but it will cost you. Depending on ...

This means your MacBook does not recognise the battery. Maybe it's not installed properly? https://support.apple.com/kb/PH18598?locale=en_US

The battery status of bluetooth connected devices is usually displayed when you click on the bluetooth menu bar icon (the icons in the top right). I might be slightly mistaken: It could also be in a submenu of said menu. You might need to enable the icon. This can be done in System Preferences/Bluetooth → Show Bluetooth in menu bar.

Unless there is a problem with the battery itself you can likely use your Mac (laptop, I presume) indefinately. I have seen that done at a number of places with Macs and PCs used as a "spare" computer. I will usually remove the battery from the laptop (if possible) to avoid the battery causing any damage to the computer, but depending on the Mac that may ...

Neither the device nor iOS stores that information anywhere. The capacity of a Lithium-Ion battery is simply based on the Voltage that the battery is currently outputting. Take a look at a Voltage over time chart for Li-Ion batteries. More information about determining capacities for Li-Ion batteries can be found here. iOS does, however, store approximately ...

If you are carrying the Macbook from outside (cold) to inside (warm & humid), you may want to consider bagging the Macbook in a sealed plastic bag (Ziplock or similar), so the condensate will form on outside of the bag, not the Macbook. If the Macbook is in a case, a bag, or sleeve, the case should supply some insulation to shield the Macbook from the ...

From Apple Support: Find the right power adapter and cord for your Mac notebook Power adapters for Apple notebooks are available in 29W, 45W, 60W, and 85W varieties. You should use the appropriate wattage power adapter for your Apple notebook. You can use a compatible higher wattage adapter without issue, but it won't make your computer charge ...

It will be fine. The MacBook Pro will charge with the Air's charger well; it will just be slower than if it was on its original charger. One can even charge a MacBook Air with the charger for the MacBook Pro, if one wanted to. I have attempted this myself and have had no problems.
